- VOCs Volatile Organic Compounds
- thinners for paints and other coatings contain hazardous ingredients such as Methyl Ethyl Ketone (MEK), isopropyl alcohol, methanol, mak, butyl cellusolve, petroleum naptha, and toluene. While such paints containing such ingredients perform adequately, their use of these hazardous ingredients is a major disadvantage and paints containing such ingredients are prohibited in government regulated areas when the paint includes more than 25 grams per liter of VOCs. While acetone alone can be used as a thinner, it is too volatile for many coatings when used as the sole thinner. In hot areas, if an acetone thinned coating is sprayed onto a surface, it can partially dry before the spray hits the material being coated.

Description
- The present application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/690,382 filed Jun. 10, 2005 and is a Continuation In Part of U.S. patent application Ser. No. 11/450,726 filed Jun. 09, 2006, which applications are incorporated in their entirety herein by reference.
- The present invention relates to low vapor pressure paint thinners and in particular to a paint thinner containing less than 25 grams per liter of Volatile Organic Compounds (VOCs).
- Many known thinners for paints and other coatings contain hazardous ingredients such as Methyl Ethyl Ketone (MEK), isopropyl alcohol, methanol, mak, butyl cellusolve, petroleum naptha, and toluene. While such paints containing such ingredients perform adequately, their use of these hazardous ingredients is a major disadvantage and paints containing such ingredients are prohibited in government regulated areas when the paint includes more than 25 grams per liter of VOCs. While acetone alone can be used as a thinner, it is too volatile for many coatings when used as the sole thinner. In hot areas, if an acetone thinned coating is sprayed onto a surface, it can partially dry before the spray hits the material being coated. Because paints necessarily include a thinner to reduce their viscosity, a thinner providing less than 25 grams per liter of VOCs is needed.
- The present invention addresses the above and other needs by providing a paint thinner and cleaner which includes a methyl soy ester and dibasic ester and satisfies a less than 25 grams per liter Volatile Organic Compound (VOC) rating which permits the thinner and cleaner to be used for cleaning and thinning in government regulated areas. Requirements for reducing VOCs are well recognized. The paint thinner and cleaner of the present invention performs as well as products (for example, hydrocarbon based thinners) having greater than 25 grams per liter VOC products. Further, the paint thinner and cleaner according to the present invention has less than one tenth of the hazardous ingredients present in the other paint thinners. The paint thinner and cleaner is suitable for reducing water and oil based coatings and material.
- In accordance with one aspect of the invention, there is provided a water based water and oil based paint thinner comprising between 50 and 90 percent by volume of base deionized water, between one and ten percent by volume of methyl soy ester material, and between one and ten percent by volume of dibasic ester.
- In accordance with another aspect of the invention, there is provided a water based cleaner comprising between 50 and 90 percent by volume of base deionized water, between one and ten percent by volume of methyl soy ester material, and between one and ten percent by volume of dibasic ester.
- The following description is of the best mode presently contemplated for carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of describing one or more preferred embodiments of the invention. The scope of the invention should be determined with reference to the claims.
- The South Coast Air Quality Management District (South Coast AQMD) has adopted the most stringent air quality regulations in the United States.

- 2) preferably between one and ten percent by volume of methyl soy ester material and more preferably between one and five percent by volume of the methyl soy ester material (added to the base to give dissolving power for the purpose of cleaning and reducing water and oil based coatings and material); and
- 3) preferably between one and ten percent by volume of dibasic ester and more preferably between one and five percent by volume of the dibasic ester (added to the base to give dissolving power for the purpose of cleaning and reducing water and oil based coatings and material);
- The paint thinner and cleaner of the present invention preferably includes ingredients selected from the following two ingredients:

- The aliphatic hydrocarbon preferably has a flash point between 20 and 150 degree Fahrenheit. Various combination of essential ingredients 4-15 may be utilized to attain the required drying profile and stay under the required 25 grams per liter of VOCs, and any combination of ingredients including ingredients 1-3 in the cited amounts and a combination of ingredients 4-15 resulting in less than 25 grams per liter of VOCs is intended to come within the scope of the present invention. Further, any combination of essential ingredients including ingredients 1-3 in the cited amounts and a combination of ingredients equivalent to ingredients 4-15 resulting in less than 25 grams per liter of VOCs is intended to come within the scope of the present invention.
- A preferred methyl soy ester material comprising a soy based emulsion is sold under the trademarks SG5000E and SG1000E by Soy Technologies, LLC of Nichokasville, Ky. 40356. This soy based ester is a combination of soybean methyl esters dibasic esters and triethanolamine. The soy based methyl ester is a mixture of hexadecanoic acid, octadecanoic acid, 9-octadecenoic acid (Z)-, 9, 12-Octadecadienoic acid (Z,Z)- and 9. 12, 15-Octadecatrienoic acid (9Z. 12Z. 15Z). The dibasic ester is a mixture of dimethyl glutarate, dimethyl adipate and dimethyl succinate.
- The result is a thinner and cleaner which is not only useful in reducing or thinning of coatings and most all water and oil based material, but is also useful for cleaning. When used as a cleaner, the solution leaves a barrier which helps prevent rust on metal and extends the life of a natural bristle brush or lamb's wool roller. The thinner and cleaner at the same time complies with government air regulations and is very beneficial to the environment.
- While the invention herein disclosed has been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
